In the accompanying drawings, A represents the head of the stud; B, the post, provided at its lower end with the annular groove a, which is adapted for engagement with the catches (J O of the shoe. D is formed of the plate b,which is struck up with a rim f, the supporting-plate c, which is struck up with the raised posts d d d, which serve to support the front plate 6, the several parts being secured together by turning over the edge of the rim f. The plate 0 is also provided with a perforation g, adapted to'reccive the lower end h of the post B.
